Has the human alarm been sounded? Scientist: 90% genes of Brazilian mystery virus have never been seen before?

2020 seems to be a year of disaster in the world. From Australian wildfires and floods to China's pneumonia epidemic, it has been widely concerned by all countries. However, one wave is not flat, another is rising. A few days ago, an unknown disease broke out in Nigeria, killing 47 people. This time Brazil joined in the role of the tragic world, sending out reports that an unprecedented virus had been found.
According to sciencealert, the supervirus was found in the muddy water of an artificial lake in Belo Horizonte, Brazil. They named it Yarra virus. It is called super virus because the virus is composed of nearly 80 nano particles (normal virus size), which can be called megavirus.
What's even more remarkable is that. The genome of the Brazilian virus found this time is very unique. Scientists compared 8500 data in the virus metagenomic database and found that only six of the Yala virus genes found this time are the same as the existing genes. 90% of the genes have no homologous genes, which can not be recognized at all and become the so-called orphan genes.

Such a complex biological relationship coupled with a rich variety of virus species, so the gene exchange between viruses and the generation of many human gene species that are not clear is also reasonable. At present, 4958 kinds of viruses have been known, but the research of a large number of new viruses needs to be improved.
In addition, amoeba has a short reproductive cycle, rapid virus variation, and the complex virus environment of amoeba, which further increases the difficulty of virus isolation, and the analysis of genes is far behind the speed of virus variation, so scientists have not invested much in this field. So it's no surprise that this discovery shocked the public
The Brazilian virus discovered this time actually belongs to one of the NCLDV viruses. We are familiar with poxviridae. Smallpox and infectious verruca virus belong to this family. I believe that smallpox virus, once a human nightmare, is no stranger to us all. From these aspects, the discovery of the Brazilian giant Yarra virus, which is a step in the normal exploration of human beings, may be only the recent chain reaction that makes the Brazilian virus event amplified.
However, let's analyze the reasons for the frequent occurrence of virus and other events from another perspective. Previous scientists have said that the earth may enter the El Nino year in 2020. Again, the temperature in some areas will be extremely hot compared with the same period, while the coming La Nina phenomenon will sharply lower the temperature everywhere. This kind of climate is unusual and repeated, and it is not the cause of frequent disasters in many countries.
Due to human activities, the atmospheric circulation may be disturbed abnormally, the weather is more arid, and the rainstorm is continuous, which may change the growth environment that the virus was not suitable for. The survival of the fittest in the natural law may be more obvious at this time, the speed of virus mutation will be accelerated, and the chagrin of human will be increased. As for the fate of human and virus, who can know, but it can be sure that human beings can only eat the consequences of destroying the environment.
